Much like development at the City's growth fringe, new infrastructure can be an important issue for infill of vacant lots, redevelopment of existing properties, and adaptive reuse of buildings. Examples of water and wastewater improvements that may be required for these kinds of development include:.
Inadequate Capacity In Existing Water Lines
Existing water distribution lines are smaller and older, and may not be able to provide adequate water volumes or fire flow pressures. Residential or commercial redevelopment may require the construction of larger lines that connect into existing lines. Generally, these lines need to be 'looped' or connected to two different larger lines to maintain water pressures rather than just adding a new line along the property.
Existing Substandard Water Lines
The City requires construction of water distribution lines along the property boundaries of virtually all types of new development or redevelopment. Existing older substandard water mains will not eliminate this requirement. These lines were installed many decades ago, are gradually deteriorating, and are not designed to accommodate the types of density and land use that are occurring with redevelopment.
Inadequate Capacity In Sewers
Infill and redevelopment may generate more wastewater than the carrying capacity of the sewer lines, either adjacent to the development or further downstream. If infill or redevelopment causes sewer lines, interceptors or lift stations to reach or exceed capacity, the necessary improvements would need to be made to ensure those bottlenecks are eliminated.
Limitations On Access To Nearby Sewers
In some cases a sewer will exist in a nearby location, but will not be accessible because of physical constraints such as grade issues or utility barriers where a connection cannot meet the City's system design standards.
